Description

A vehicle-mounted intelligent safety warning system

technical field

The invention relates to a driving safety early warning system, in particular to a vehicle-mounted intelligent safety early warning system.

Background technique

Vehicle rear-end collision accidents are very frequent during driving. The main reason is that it is difficult for the driver to judge the actual distance between the vehicle in front or the vehicle behind. It is more difficult for the driver to judge the distance between the car behind and the workshop. Moreover, different drivers also have certain differences in driving speed and braking reaction time. For example, when a skilled driver is driving at a speed of 100 kilometers per hour, keeping the distance at about 100 meters can be a safe driving distance, while for a novice driver, this safe distance may need to be expanded to nearly 150 meters. Therefore, if the driver makes a wrong judgment on the actual distance between the vehicles, once the emergency brake light is encountered, rear-end collisions may occur, which may cause damage to the vehicle, or may endanger the lives of the people on board. Furthermore, some people proposed to install an anti-rear-collision system on the car, but the existing anti-rear-collision system cannot monitor and display the distance between front and rear vehicles in real time during driving, and intelligently remind the vehicle behind to keep the distance between vehicles, so that it cannot meet the needs of driving safety.

Therefore, the prior art still needs to be improved and developed.

Detailed ways

In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

As shown in Figure 1, the vehicle-mounted intelligent safety early warning system provided by the present invention comprises detection module, analysis control module, display module, input setting module and alarm module; Detection module comprises GPS submodule and infrared detection submodule again, GPS submodule is used In order to obtain the speed of the vehicle, the infrared detection sub-module specifically includes a speed detection device and a distance detection device (not shown in the figure), and the speed detection device and the distance detection device can be specifically configured as an infrared speedometer and a distance sensor respectively. There are at least two infrared speedometers, which are respectively arranged at the front end and the rear end of the vehicle, and are used to test the relative speed between the vehicle and the front and rear vehicles; there are at least two distance sensors, which are respectively arranged at the front and rear of the vehicle Two surfaces are used to test the relative distance between the vehicle and the front and rear vehicles, and can also be set to four or more, which are respectively set on the front, rear, left and right surfaces of the vehicle; the GPS sub-module , the speed detection device and the distance detection device are all electrically connected to the analysis control module; the display module is a vehicle-mounted display arranged within the visible range in front of the driver, and the display content of the vehicle-mounted display includes information on the distance between the vehicle and other vehicles around the vehicle body, Vehicle speed information, and other information related to driving safety. The alarm module includes an in-vehicle alarm and a warning display. It can be set as sound and/or video alarm or other types of alarms; the early warning display is set at the rear of the vehicle and can be specifically set as an LED display, which is mainly used to display early warning information to the vehicles behind. The on-vehicle display, in-vehicle alarm and early warning display are also electrically connected to the analysis control module; the input setting device is electrically connected to the analysis control module, and is specifically set as a keyboard input device or other input device, which is fixed in the cab to facilitate the driver to input In the position of operation, the driver can personalize the settings of various safety parameters according to his own situation, such as the safety distance and speed between the front and rear vehicles for safety reminders or automatic braking, and other parameters can be set by himself; the analysis control module is in addition to the above-mentioned In addition to the electrical connection of each module, it is also electrically connected to the control system of the vehicle. When an emergency occurs, the analysis and control module automatically controls the vehicle to handle the emergency.

In the vehicle-mounted intelligent safety warning system, first, the driver inputs safety parameters to the analysis control module through the input setting module. For example, the safety parameters are set to be 100 meters when the distance between the vehicle and the vehicle in front is less than or equal to 100 meters, and the vehicle speed is 100 meters. When the distance between the vehicle and the vehicle behind is less than or equal to 100 meters, an early warning message will be issued to remind the driver of the vehicle behind to slow down and remind the driver of the vehicle to avoid rushing. brake. After the safety parameters are pre-set, the GPS sub-module monitors the speed of the vehicle in real time during driving, and transmits the speed information to the analysis control module; the infrared speedometer monitors the relative speed between the front and rear vehicles and the vehicle, and the infrared The speedometer transmits the measured data to the analysis control module in real time, and pre-sets the positive and negative values of the relative speed, then the speed of the front and rear vehicles = the speed of the vehicle + relative speed; the distance sensor can monitor the front and rear of the vehicle , the distance between the left and right vehicles and the vehicle, and transmit the measured data to the analysis control module in real time; the analysis control module receives the real-time data transmitted by the above-mentioned modules and displays them in real time on the display module. At the same time, the analysis control module will also make logical judgments based on the preset safety parameters. When the real-time data shows the range value of the preset safety parameters, it will immediately send an alarm signal to the alarm module, and the alarm module will immediately report to the driver of the vehicle. The driver can send a warning signal to slow down or send a warning signal to the driver behind to keep the distance between vehicles. In an emergency, the analysis control module can also directly control the vehicle control system for emergency braking, steering and other safety operations.

As can be seen from the foregoing embodiments, different drivers can use the vehicle-mounted intelligent safety warning system provided by the present invention to pre-set their own safety parameters according to their different driving characteristics, and the vehicle-mounted intelligent safety warning system will monitor the vehicle in real time during driving. The speed of the front and rear vehicles, the distance between the vehicle and the front and rear vehicles are tested, and the real-time data is displayed to the driver for reference. When the real-time data falls within the preset safety parameter range, the Send an early warning signal to the driver of the vehicle or the driver of the rear vehicle, thereby greatly improving the driving safety and effectively reducing the probability of rear-end collision accidents during driving.

It should be understood that the application of the present invention is not limited to the above-mentioned examples, and those skilled in the art can make improvements or transformations according to the above-mentioned descriptions, for example, all functional extensions and improvements made according to the principles of the present invention, all of which Improvements and transformations should belong to the scope of protection of the appended claims of the present invention.
